Colonel-in-chief is a ceremonial position in a military regiment. It is in common use in several Commonwealth armies, where it is held by the regiment's patron, usually a member of the royal family.
Some armed forces take a light-hearted approach to the position, appointing animals or characters as colonel-in-chief. The Norwegian Army, for example, appointed a king penguin named Sir Nils Olav as a colonel-in-chief.[1][2]
